Technical field
The present invention relates to shopping cart series, it is formed by at least two different shopping carts, the basket that each described shopping cart has underframe and supported by described underframe, wherein, identical shopping cart can in a row be parked by this way so that during its basket and its underframe partly be inserted in each other, and at least one wherein is set is positioned at below the basket bottom and the exterior connecting device of basket sidewall, described connecting device has and allows basket immovably is fastened to point of connection on the underframe in the assembly manipulation process.
The invention still further relates to a kind of shopping cart, it is suitable for forming shopping cart series, has described just now technical characterictic.
Background technology
Shopping cart series is known, wherein the basket of different length and/or height can be selected to be connected to same underframe.The underframe of different length and/or height may be provided for identical basket on the contrary.In these cases, the kind of connecting device and being provided with is by this way selected, so that form general point of connection, described point of connection is positioned at all the time, is positioned to small part, on the sidewall of basket.
German utility model DE 299 07 769 U1 described a kind of can stacked shopping cart, wherein be provided with between underframe and basket middleware as connecting device, and lower region thereof is provided with those connecting devices that are positioned in a known way on the basket sidewall, and is furnished with this connecting device that is positioned in a known way on the underframe in the upper area of described middleware successively.So, produce the shopping cart that its basket has low relatively structure if necessary, then need to use the middleware of initial description, therefore to arrange low basket, so that propulsion equipment also is arranged on the height that is suitable for the shopping cart user in higher mode.If expectation is used high relatively basket with identical underframe, then need not to use middleware, so because propulsion equipment is because the higher height of basket is positioned at suitable height all the time.
For these two shopping carts that are combined together to form shopping cart series, at least some connecting devices are positioned on the sidewall of basket all the time.In this solution, sidewall is also as the device that basket is fastened on the underframe.
Middleware self becomes the parts that increase cost because its have also must be arranged on the basket and underframe on parts.Therefore, cast aside other and do not say, need with molding member structure and must be once two be welded on the underframe and two four guide rails (rail) that are welded on the middleware once.For producing such shopping cart in cost-effective mode, the middleware of the type is unfavorable.
UK Patent Application GB 2 383 307A have described a kind of shopping cart, and it is designed for the wheelchair user, and can be fastened to wheelchair, and its basket is mounted to and can rotates around vertical axis.The movable connecting device that the rotation of basket is installed by described basket being connected to underframe and being designed to ball bearing of main shaft becomes possibility.Described ball bearing of main shaft is between the bottom and underframe of basket.The basket of this shopping cart is a cylinder design, so that it may make the wheelchair user by its rotation is loaded onto with more than one the described basket of naming a person for a particular job.In the patent application of being mentioned, should be noted also that to replace cylindrical basket, also can use the basket of conventional confguration type, so that described basket is fastened to underframe in rotatable mode equally.The explanation about such assembly manipulation of any kind is not passed in the patent application of being mentioned, and actual conditions are to need such assembly manipulation can down basket being connected to underframe the auxiliary of ball bearing of main shaft, and such assembly manipulation difficulty relatively after all.Described patent specification is also without any explanation whether can be inserted into each other about its basket and underframe.At last, can not find that also shopping cart series about the type of initial description is any suggestion that how is formed by the shopping cart of just having described.
European patent application EP 1 093 987 A2 have described shopping cart, and U-shaped clamp (U-shaped clip) on its connecting device is welded to below the basket bottom by two and clasp joint ring (hook-ineyelet) and the dead ring (fastening eyelet) that is welded on the underframe form.For basket is fastened to underframe, four U-shaped clamps hook in the clasp joint ring, be fixed to dead ring then and prevent to separate under independent securing device is auxiliary.The basket of shopping cart is fastened to two U-shaped clamps of these method needs of underframe, four clasp joint rings, four dead rings and at least four other securing devices, thereby the design-calculated setting has to be considered to a large amount of parts of needs by this way, and so it is and expensive.Because shopping cart is categorized as mass produced item, so each cost increase, though little, to add up, summation is unacceptable cost factor.As observed in conjunction with the initial british patent specification of describing, how that can not find any kind equally in EP 1 093 987 A2 may form explanation and proposal corresponding to the shopping cart series of the series of mentioning at first by described shopping cart about it.
Do not consider the prior art described just now, and cast aside other and do not say, only for the reason that reduces cost, the maker of each shopping cart the try one's best different baskets that keep limited and/or the kind of different underframe.On the other hand, recognize the needs of supermarket chain, according to the needs of its supermarket chain, supermarket chain is wondered complete and its marketing ideas coupling of its shopping cart that is using.Up to the present, these marketing ideas have caused the development of the shopping cart form of maximum kinds.As a result, the maker of shopping cart must keep the production of the shopping cart of the most basic a lot of types, surviving in market.
What this point need be spoken more is, in maintenance process, only allow to design cooresponding basket and/or underframe is changed by the shopping cart of base and basket assembling, and for each maker, described connection design has nothing in common with each other with coming from that same manufacturer is produced and therefore being connected with it.Therefore this limited the following ability of supermarket chain:
Do not rely on particular manufacturer and obtain basket and/or underframe; Or
Obtain different in all cases and basket and/or underframe gratifying quality and service life; Or
If theory changes, then only change basket or underframe, rather than change whole shopping cart; Or it is last
Selling at no time again need be by the company of described parts or the basket or the underframe of other users maintenance.
As a result, in the institute that is mentioned is restricted, the purchase that is produced by the use of shopping cart, maintenance, utilize and the total expenses handled remains on high level, this is mainly determined by maker again.For supermarket chain, because expensive, it is unfavorable that this makes himself experience for a long time.
Summary of the invention
Adopt the prior art of initial description and the departure point of the situation of describing, the objective of the invention is to further develop by this way the shopping cart series of general type, so that reducing manufacturing cost, and preferably reduce maintenance, utilize again and processing cost the time, make the quantity that increases different shopping carts become possibility; Can also make do not relying under the situation of maker that supermarket chain can provide, construct or change new shopping cart from a large amount of baskets and underframe, and correspondingly provides, constructs or change new shopping cart series thus.
Solution about shopping cart series purpose is such fact, be that different shopping cart is being distinguished aspect the different in width of the different in width of its basket or its underframe at least mutually, and be such fact, promptly at least with the setting of the cooresponding point of connection of basket or, at least be identical in all shopping carts of being arranged on of the cooresponding point of connection of underframe.

Fig. 5 demonstrates, and assisting down of single connecting device, may connect between underframe 3 and basket 9, and described single connecting device not only is connected to basket 9 but also be connected to underframe 3 in inseparable mode, and perhaps it can slide on basket 9 and the underframe 3.The exemplary embodiment according to Fig. 9 that will be described below can be classified as such.
Fig. 6 has shown shopping cart series 1 with plan view, and for the sake of simplicity, described shopping cart series 1 only comprises three different shopping carts 2.Underframe 3 is identical under the situation of all three shopping carts 2.On the other hand, under the situation of each shopping cart 2, basket 9 is with different width dimensions design---comparing dimensions A, B and C.Under the situation of each shopping cart 2, area part 24 has been shown, the general point of connection 23 that at least one connecting device 18 wherein is set and forms thus.Simultaneously, see from above that point of connection 23 is positioned at area part 24, described area part 24 is than the maximum width E narrow (dimension D) of the basket bottom 11 that is generally trapezoidal design, and preferably the width F than the underframe of highly locating at described area part 24 to measure 3 is narrow.Accompanying drawing demonstrates the base surface area of the trapezoidal bottom 11 of basket to know mode, and it is shown by shade.The base surface area of basket bottom 11 do not comprise the sidewall 9 of basket 9 '.Can find out that in shown shopping cart 2 under the situation of the shopping cart 2 shown in the on the left side, the width of basket 9 is greater than the width of the underframe of highly locating at area part 24 to measure 3.Under the situation of the shopping cart shown in the centre 2, the underframe of measuring with corresponding manner 3 is identical with the width of basket 9, and under the situation of the shopping cart 2 that illustrates on the right, basket 9 is narrower than the width of the underframe of highly locating at area part 24 to measure 3.Assisting down of this example, can easily imagine, the basket shown in each 9 can be designed to differing heights and/or different length.In belonging to all shopping carts 2 of shopping cart series 1, connecting device 18 and point of connection 23 are arranged all the time in the same manner, preferably in center arrangement.Thereby may make different shopping cart 2 with mono-underframe size, its formation has the shopping cart series of preferred different basket size and basket capacity.
Fig. 7 has two baskets 9 of different in width to simplify the back view that view has shown shopping cart 2 shown in it.Assisting down of practical situation, advantage of the present invention becomes clear.Because statutory standards, in France, the width of shopping cart 2 can not surpass 600mm, but at least in European other countries, allows the maximum width of 650mm.The figure illustrates the shopping cart 2 under each situation, described shopping cart forms shopping cart series 1 together.May produce width is 600mm and the underframe 3 that is equipped with two connecting devices 18.Two connecting devices 18 are connected to the mode of basket 9 and underframe 3 can be according to fastening one of may mode selection of describing among Fig. 1 to 5.In any case, from the top, profile about the bottom 11 of basket 9 and described basket, at least with such selection that is provided with of basket 9 cooresponding point of connection 23, so that the basket of different in width 9 selectively is connected to one and identical underframe 3, and it is all identical corresponding to being arranged in two structure thing cars 2 of the point of connection 23 of basket 9 at least, and therefore all identical in the shopping cart 2 of all the type.This can prove in the drawings by such fact: the basket 9 with width 600mm (France) illustrates with continuous straight line, and the basket (European other countries) with width 650mm illustrates in the long and short dash line mode.The basket of last-mentioned shopping cart is at each side-prominent underframe 325mm that surpasses.In this example, shopping cart series 1 comprises at least two shopping carts 2, and it all has identical underframe, but basket 9 has different width.This solution is possible because the sidewall 9 of the basket 9 in two shopping carts 2 ' no longer with connecting device 18 mutual actions.Under every kind of situation, the distance between two connecting devices 18 is less than the maximum width of basket 9, and narrower than the width of underframe 3.
Alternate embodiments as the exemplary embodiment of describing just now, under accompanying drawing auxiliary, can easily imagine, may keep the constant width of basket 9 to use the underframe 3 of different in width simultaneously, thereby form the shopping cart series of forming by at least two different shopping carts 2.In this case, from the top, profile about described underframe 3, at least select by this way so that same basket 9 selectively is connected to the underframe 3 of different in width corresponding to the setting of the point of connection 23 of underframe 3, and all identical corresponding to being arranged in all shopping carts 2 of the point of connection 23 of underframe 3 at least.
Under accompanying drawing auxiliary, can find out, be formed on apart from a between the bottom 11 of the circle, the top of underframe 3 and basket, and this also can infer from the exemplary embodiment Fig. 9 and 11.
In order to replenish Fig. 7, Fig. 8 has shown the exemplary embodiment of describing just now with birds-eye view.May produce two connecting devices 18, it is connected to underframe 3 at a distance from each other, and basket 9 slides on described two connecting devices 18 successively.From the top, point of connection 23 is arranged in area part 24, and described area part 24 is narrower than the maximum width G of the basket bottom of highly locating at described area part 24 (or in zone) to measure 11.In this example, point of connection 23 also is positioned at the base surface area of basket bottom 11 fully, and it is by thick shadow representation.Connecting device 18 is set so that it is not removable on two lateral struts 7 or can to slide on two lateral struts 7 be favourable, described two lateral struts 7 are connected two vertical cross bars 6 of the underframe 3 in described underframe 3 upper areas 5 usually, and described two lateral struts 7 under any circumstance all exist.Thereby each connecting device 18 utilizes two lateral struts 7 to be fixed to underframe 3.Size relationship of describing among Fig. 7 and 8 and technical characterictic any shopping cart series 1 of can migrating.
Fig. 9 has shown the basket 9 of shopping cart 2 and the join domain 17 of underframe 3 with amplification view.Here the solution of Ti Chuing only is one of the design possibility that possible imagine.This solution comes from the exemplary embodiment of describing among Fig. 5.The figure illustrates the upper area 5 of underframe 3.Described underframe 3 has vertical cross bar 6 of two K/UPs in a known way.These two vertical cross bars 6 are connected by lateral struts 7, and lateral struts 7 is made by for example band steel---and also can be referring to Fig. 8.The single connecting device 18 that is made of plastics is connected to two lateral struts 7 by this way from the top with bolt-lock type or buckle-type locking mode: described two lateral struts 7 have and are arranged on the connecting device 18 and the protrusion 19 of partial engagement around it.At least one of two lateral struts 7 is equipped with the hole 8 of at least one horizontal arrangement, engages at least one and be arranged on bolt 20 on the connecting device 18 in hole 8.Described connecting device 18 thereby enter no longer the desired location that changes.In this example, connecting device 18 has four vertically arranged perforation 21, and it is designed for bolt-lock type or buckle-type locking mode and holds four protrusions on the bottom surface (underside) 12 that is arranged on basket bottom 11.Described protrusion 14 configuration examples as be arranged on basket bottom 11 as described in the component part of two folders 13 of U-shaped design-calculated on the bottom surface 12.Folder 12 and basket 9 thus are placed on the link 18 with its horizontal branch 15 in the positioning and fixing mode.Each perforation 21 has little protrusion 22, whenever is being deeply in love under the condition, and the recess 16 that is arranged on the protrusion 19 is locked in each protrusion 22.Basket 9 thereby under connecting device 18 auxiliary, be connected to underframe 3 with movable manner not.Connect shown in obtaining, connecting device 18 at first is connected to two lateral struts 7.Basket 9 is introduced in the perforation 21 down the auxiliary of its protrusion 14 then, and pushes downwards up to occurring in obtainable locking connection between protrusion 22 and the recess 16.Thereby set up can not be dynamically connected between basket 9 and the underframe 3.Here, " bolt-lock type or buckle-type locking mode connect " is generally understood as the connection that means two or more parts, and it does not for example need additional securing devices such as screw, nut, pin just can realize.As finding out from figure, general point of connection 23 is formed between lateral struts 7 and the protrusion 19, is formed between hole 8 and bolt 20, and is formed between 21 and four protrusions 14 of four perforation.These all point of connection 23 are arranged in the area part 24 that Fig. 6 or Fig. 8 describe.
Here the solution of Ti Chuing has disclosed new possibility.If connecting device 18 designs according to the housing form, then obtain a space 25 at least, described space 25 can be for example from following or enter from least one side, and be suitable for for example holding at least one parts, described parts are for example electricity and/or electronic unit, and it can widen the function of shopping cart 2.This space also can be by suitable detachable closing feature closure, to be used for for example installing or changing the purpose of electrical equipment or electronic unit.No matter be in order to ensure identification shopping cart 2 and with the affiliated relation in specific supermarket, or want to prevent that described shopping cart is stolen, also no matter be in order to limit the length of in a row stacked shopping cart 2, the use of the parts of mentioning at first in shopping cart 2 increases gradually, especially in the recent period.The parts of being mentioned all need under all these situations all the time.Owing to for the intensity reason, connecting device 18 must be big relatively, so this also must form at least one big relatively space 25, to hold these parts, described parts are preferably electrical equipment and electronic unit.Therefore for example may hold by constitute big of battery and therefore for a long time current supply, and this is just up to the present because thing that space problem can not successfully be resolved always.Electrical equipment and electronic unit hold the problem of not bringing equally because because its little size, these parts take up space now hardly.
Can should be mentioned that about this point, nature may be provided with two connecting devices 18 and replace a connecting device 18 having described just now, described two connecting devices 18 for example can be mirror image and put upside down design (mirror-inverted design), also can be, so to say that, be development, and described two connecting devices 18 have characteristic and technical characterictic that the single-piece connecting device 18 that is made of plastics of initial description is showed equally from single connecting device 18.Each of these connecting devices 18 has for example two perforation 21, is used to hold two protrusions 14.In two connecting devices 18 each also may be equipped with another bolt 20, and this another bolt 20 is bonded on another hole 8 that is arranged on another lateral struts 7.Two connecting devices 18 can thereby in each case, in reference single-piece connecting device 18 same or analogous modes, be fastened to two lateral struts 7, and it is arranged in the area part of having described 24 equally---referring to Fig. 6 and/or 8 as example.In two connecting devices 18 at least one has at least one space 25, is used to hold the parts that at least one widens shopping cart 2 functions.
Figure 10 has shown an exemplary embodiment, and wherein basket 9 can be at the auxiliary underframe 3 that is connected to shopping cart 2 down by the bolt-lock type lock mode of at least one connecting device 18.Two connecting devices 18 that keep a determining deviation weld or are fastened on the underframe 3 in for example identical with the mode that proposed in the example according to Fig. 7 mode.Each connecting device 18 is designed to be arranged in the connecting panel (web) on the edge, and the conspicuous thing that do also is to connect tabular connecting device 18 with two to be welded on two lateral struts 7---compare with Fig. 8.At its front end, each connecting device 18 has clasp joint ring 28.The back end design of each clasp joint device 18 is locking recess 29.Bar portion 26 from advance handle 10 beginnings two sidewalls 9 of basket 9 ' each the outside on extend downwards, and surpass the bottom 11 of described basket continuously downwards.Then, two bar portions 26 are with right-angled bend, and below the bottom 11 of basket to extending (lead towards oneanother) towards each other, thereby for example form single cross connecting plate 27.Basket 9 can hook in the clasp joint ring 28 by the protrusion by cross connecting plate 27 or respective design in the assembly manipulation process, so that described basket 9 enters first location.U-shaped clamp 30 is arranged on 11 bottom surfaces, basket bottom by its branch 32 with movable manner not.Described folder 30 tilts, thereby the lateral member 32 of folder 30 is provided with downwards farthest.In the assembly manipulation process, assisting down of clasp joint ring 28, basket 9 is present on two connecting devices 18, and by advancing handle 10 to push downwards, up to the lateral member 31 of folder 30 near being locked in two recesses 29 in the connecting device 18---referring to another thin portion.In this position, basket 9 is connected to underframe 3 by the bolt-lock type lock mode and with movable manner not down the auxiliary of connecting device 18.In these cases, two bar portions 26 of the branch 32 of folder 30 and basket 9 place near the outside of connecting device 18.See that from above point of connection 23 between basket 9 and the connecting device 18 with reference to the profile of basket 9 and with reference to its position, is selected by this way at least, forms shopping cart series so that the basket of different in width selectively is connected to underframe 3.Just now the point of connection of mentioning 23 is preferably placed in the profile of basket bottom 11.This can be applicable to the point of connection 23 between underframe 3 and connecting device 18 too.Under the situation of all shopping carts 2 that form shopping cart series 1, the setting of the design of connecting device 18 and point of connection 23 is identical all the time, and this may be considered as cross connecting plate 27 and lateral member 31 to have the connecting device 18 of point of connection 23 equally.
At last, Figure 11 has shown two identical shopping carts 2 from shopping cart series 1, during it inserts each other in the conserve space mode.At least one connecting device 18 with attached point of connection 23 is arranged on each shopping cart 2.This at least one connecting device 18 according to as described in basket 9 is connected to underframe 3.During basket 9 and underframe 3 all partly insert each other.The connecting device 18 of two shopping carts 2 clashes into each other.The length that size S represents so-called " stacked distance (stacking distanve) ", it obtains when two shopping carts 2 can not further insert each other.In this example, the length of each connecting device 18 is stacked apart from S corresponding to this.As a supplement, this size S also is illustrated between two propelling handles 10 on the shopping cart 2, occurs in all same positions or the some place on two shopping carts 2 so that described size S to be described.
As summary, also can be observed, the description of solution of the present invention has emphasized naturally that those proofs are to realizing particularly advantageous characteristics of the present invention.These comprise such fact: the setting of connecting device 18 is identical usually in all shopping carts 2 with the position of attached point of connection.But, the present invention allow shopping cart series (1) and the shopping cart 2 that is suitable for forming described series only with the setting of the cooresponding point of connection of basket (9) (23) or only identical with being provided with of the cooresponding point of connection 23 of underframe (3).This means, if it is identical corresponding to being provided with of the point of connection 23 of basket 9, then may have diverse design corresponding to the setting of the point of connection 23 of underframe 3, and alternately, under the situation of the different shopping carts 2 that belong to shopping cart series (1), if this should prove favourable under each situation, then vice versa.
